STICK-PIN.

Patented Nov. 20, 1906.

Application filed March 1, 1906. Serial No. 803.726.

T aZZ whom it may concern:

Be it known that I, MICHAEL KENNEDY, a citizen of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented a certain new and useful Improvement in Stick-Pins, of which the following is a specification.

My invention relates to jewelry stick-pins made in two pieces and united without the use of solder. 4

In the manufacture of this class of articles it has heretofore been common to strike up the rear surface of the blank or head member of the pin in such manner as to dispose an annular flange-hub to receive and be swaged upon the cylindrical end portion of the pin member, with the result that after the article is used by the wearer its members eventually become loose and the head member having the design or configuration formed therein stands in an irregular position with relation to the pin member.

In the accompanying sheet of drawings, Figure 1 represents a rear perspective view of a stick-pin as embodying my improvement. Fig. 2 is a top plan view of the blank which forms the head member of the stick-pin. Fig. 3 is a sectional view taken in line as as of the same. Fig. 4. is a top plan view of the blank or head member showing my improved socket for securing the pin member therein. Fig. 5 is a sectional view taken in line y y of the same. Fig. 6 is a view of the stick-pin, partly in section and partly in elevation, showing the manner of securing its two members together; and Fig. 7 is a top plan sectional view taken in line 2 z of the same.

Like reference characters indicate like parts.

In the manufacture of my improved stickpin the blank or head member a is first placed over a fixed die-plate to receive the blow of a plunger which causes the matrix of said die to give the desired figure design upon its front face, as at a, after which a second blow is given upon the exposed rear face of said blank by a suitable die-block which comes down forcibly and causes the metal to upset from the blank and take the form of a flange-hub a provided with a square-shape recess or socket (L in the manner shown in Figs. 4 and 5.

The pin member I), prior to being bent, as shown in Fig. 1, is loosely mounted in an opening formed in a secondary or forcer die, and the butt-end portion of this pin is flattened so as to dispose a square shape in crosssection, and which portion of said pin is made to fit within the socket of the hub (L This pin b is provided with a V-shaped groove b which extends around its flattened portion and in a plane near to the outer edge of the flange that forms the hub a After the butt-end or shank portion of the pin has found its resting place within the hub the secondary die comes down forcibly and swages the outer edges of the hub 0 within the groove 1) of the pin, and thereby securing both members firmly together and at the same time preventing them from ever turning upon each other.

After the parts are thus secured together the pin is bent in the usual manner with relation to the ornamental figure design of the head member.

What I claim, and desire to secure by Letters Patent, is-

A stick-pin, consisting in the combination with the head member, having on its rear surface a hub struck up or swaged from the material thereof and having a square socket therein, of a pin member having a square shank fitted to said socket and having also retaining-grooves into which the upper edge of said socketed hub enters, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
